Patented Jan. 8, 1952 `UNITED STATES PATENTA OFFICE CORN PLANTER WHEEL SHIELD Clarence P. Geyer, Mason City, Iowa Application September 9, 1949, Serial No. 114,861

3 Claims.

This invention relates to agricultural implements, and more particularly to a shield or fender for use on the wheel of a corn planter to prevent clods of earth or corn stalks and similar debris from becoming entangled with the planter wheel and preventing its normal rotary movement.

A main object of the invention is to provide a novel and improved shield device for a corn planter wheel, such shield device being very simple in construction, being easy to install on a planter wheel, and preventing clods of earth and other debris from becoming entangled in the planter wheel and interfering with its proper rotation.

A further object of the invention is to provide an improved shield or fender device for a corn planter wheeLlsaid device being very inexpensive to manufacture, being rugged in construction, providing protection against loosened soil, stalk fragments, and other debris, from interfering with the normal rotary movement of the corn planter wheel, and acting to prevent interference of debris with the planter wheel, whereby the planter wheel is prevented from skidding, and whereby excessive depth of planting of the seed is avoided.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure l is a side elevational view of a corn planter wheel provided with a shield device constructed in accordance with the present invention;

Figure 2 is a cross-sectional view taken on line 2--2 of Figure 1;

Figure 3 is an enlarged cross-sectional detail view taken on line 3-3 of Figure l.

Referring to the drawings, II generally designates a conventional corn planter wheel of the type having a pair of spaced. rim segments I2, I2 connected by U -shaped loop members I 3 and provided with a hub I4 connected to the brackets I3 by radial bolt members I5. The hub I4 is rotatably mounted on a transverse shaft member I5 which is secured at its respective ends to the drawbar elements Il, I1 in a conventional manner.

Designated at I8, I8 are respective shield mem bers secured to the respective drawbar members I'I and covering the major portion of the lower half of the respective wheel rim segments I2, I2. Each shield member I8 comprises a semi-circular lower portion I 9 which is downwardly and inwardly inclined, as shown in Figure 2, and verti-Y cal top portions 20 and 2l at the respective rear and forward portions of the shield devicethe top elements 20 and 2| being separated by an intermediate clearance notch formed in the member I8, said notch being shown at 22 and delining a clearance space through which the shaft member I' passes. The rear element 20 is secured to the inside surface of the adjacent drawbar element I'I by means of a bolt 23. The forward element 2 I is secured to the inside surface of the adjacent drawbar element I1 -by a strap member 24 which straddles the drawbar element II and which is formed with end tabs 25, 25 secured by bolts 2S, 26 to the element 2I.

In operation, the wheel II is drawn along the path onto which it is desired to distribute the seed, the shield elements I8, I8 extending downwardly and inwardly with respect to the respective rim members I2, I2 of the wheel, as shown in Figure 2, the peripheral outer margins of the respective shields being closely adjacent to the respective rim members I2, I2, whereby entry of clods and debris into the space between the rim members I2, I 2 is prevented. Since the clods and other debris cannot enter between the rim elements I2, I2, this material cannot interfere with the normal rotation of the planting wheel.

The lower elements I9 of the shields are preferably bent inwardly at an angle of approximately 20 to the vertical. 'I'he shield may be made of any suitable material, for example, sheet steel or the like.

While a specic embodiment of a wheel shield for corn planters has been disclosed in the foregoing description, it will -be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as dened by the scope of the appended claims.

What is claimed is:

1. In a corn planter, a planting wheel comprising a pair of spaced rim members, means connecting said rim members and includingI a hub, a shaft extending rotatably through said hub, a pair of drawbar elements secured to the ends of said shaft, and respective semi-circular shield elements secured at their straight edges to said drawbar elements and extending downwardly and inwardly therefrom, the semi-circular margins of said shield elements extending inwardly and in concentric arrangement with their respective rim members.

2. In a planter, a planting wheel comprising a pair of spaced rim members, means connecting said rim members and including a center hub, a shaft rotatably disposed through said hub and having drawbars secured on its opposing ends, and respective semi-circular shield elements secured adjacent their straightredges to the drawbar and depending from the drawbars, said shield elements being bent inwardly from the drawbars and having their semi-circular margins disposed adjacent to the lower portions of the rims and in concentric arrangement therewith, vertical tabs projecting from the front and rearportions of the straight edges of the shields and disposed in parallel engagement of the inner surface of the drawbars and means connecting said tabs to the drawbars. Y

v3. In a planter, a planting wheel 4comprising pair of spaced rim members, means 'connecting said rim members and including a center hub, a shaft rotatably disposed through said hub and having drawbars secured on its opposing ends,

land respective semi-circular :shield 'elements carried by the drawbars, upstanding 4tabs .formed on the front and rear portions of the straight edges of the shields, means axing said tabs to the inner surfaces of the drawbars, said shields depending from the drawbars and being lbent in- Wardly, and said semi-circular margins of the shields being positioned centrally of the lower portions of the hub members and in concentric spaced arrangement therewith.
